Application filed #Tune 9.6, 1918. Serial No. 241,948.

To all ywho/11y it' may concern.'

Be it known that l, Banner F. KivonLocI-r, a citizen of the United States, residing,- at Pittsburgh, in the county ot' Allegheny and State of Pennsylvania, have invented certain new and useful l'niproveinents in Attaching Devices for Noinkid Chains, ot which the following is a specification, reference being had to the accompanying d rawings.

rlhis invention relates to an attaching device for non-skid chains, and has for its priinary object to provide certain improvements in my original invention as shown and described in application Serial No, Ql,

filed February 21. 1918, .whereby the durability and general efficiency of the device in practical use will be materially enhanced.

lt. is a more particular object of the invention to provide a device for the above urpose embodying spaced attaching hooks or the terminal links of the chain, and 'a simplified and improved form of latch elethe casual disengagement ot the chain link therefrom.

As a specific item of improvement in my original invention above referred to, l contemplate the provision of a one-piece resilient latch element suitably fixed at one of its ends to the body ot the attachment, one of the link receiving lugs being notched or slotted in one side to receive the jfree end of said latch element, and said element being provided with terminal means whereby it may be conveniently manipulated and engaged in said slot or disengaged therefrom.

nd it is a further general object oi' the invention to provide an vattaching device for noinskid chains whereby the chains may be very yeasily ind quickly applied to or rcmoved rom the tire of a vehicle wheel, the device as a, whole being ot exceedingly simple construction, not liable to get. out of order, and capableof manufacture at, comparatively small cost.

With the above and other objects in view, the invention consists in the improved con struction, combination and relativearrangement of the several parts as will be hereinafter more fully described, subsequently claimed and illustrated in the accompanyint;r dra-Ninn` in n'heh similar reference characters designate corresponding parts throughout the several views, and wherein Figure l is a transverse sectional view lugs to prevent i through the tire and felly of a vehicle wheel, illustrating one embodiment o the invention and showing the tread chain applied to the wheel tire;

Fig. 2 is a plan view of the attachment, the latch element being illustrated in dotted lines in its released position;

Fig. 3 is a sectional view taken on the line lL-3 oi Fig. 2; and

Fig. l is an end elevation.

Referring in detail to the drawing, 5 designates the body bar, which is generally of rectangular form and may be of any desired width and thickness. Upon one end of this bar, an angularly disposed rectangular post (l is integrally. formed and is provided. with a cylindrical threaded rod one side of the post` 6 and extends longi tudinally therefrom in a plane parallel to the plane of the body bar 5.

ll-pon the other end of the bar 5, a cylindrical lun` 9 is formed, said lug preferably being provided with a reduced end portion 10. ln one side of this reduced end portion of the lug- 9. a transversely extending Slot or recess ll is formed, said slot 'preferably being oi a depth slightly exceeding the di ameter of the reduced end of said lug.- vThis end of the body bar 5 is likewise formed with an attaching plate i2 extending from the opposite side of the bar with respect to the lug fl. This plate is formed with spaced screw receiving openings 13, whereby it may be securely attached to one side 0i the wheel telly, indicated at l?.

ln conjunction with the cylindrical lug 9. a hook-shaped lug 14 is employed, said lug,l projecting from one side of an interiorly threaded boss l5. which is adjustablv"en raged upon the threaded rod 8. An attaching plate 16 for the hook f14 is integrally formed with the Vupper side of the boss l5 and is likewise provided with' screw receiving openings 17 whereby said plate may be securely fixed to the o posite side face o' the wheel telly. .lt wi l be noted that the' bill of the hook i4 projects inwardly toward the post 6 on the body bar 5. and the boss i5` is of such diameter that it engages over the inner face of the wheel telly. It will. of course. he understood that in thel application ot the device. the platev lll which isv provided with thc ingr 14 is first. adjusted on the threaded rod 8 until said plate is properly terminal, indicated at 7. 8 is also integrally formed with lill@ les Askid tire chain arial this` chain ie provided with terminal linlcl l) adapted to he respeci' vel): engaged willi l'he cilindrici lng; 3

Thus, it is not necessary to hold the ,alzch against, a return movement :ind the free end of the .latch rod entirel)- ont of the wily so that the tei'- niinal link of the chain cao readily diec gaged *from the attaching; lng. Y

From the foregoing description, taken in connection with the ai ,menig/'ing heaving the cohetruction, inner of operation acci several edvana'im of my invention will he .i ite normel poappreciated that l have materially improved the device as shown in mv prior application above referred to and also greatly increased the durability and sci'vieezihility thereof by simplifying the latch construction in the manner tleeciihed.This latch device, however, have found lo be very efficient and reliable in practical use and capable of effectnally resisting casual Shocks or jars which might have a tendency to clisengage the latch from the :teehing lug .md release the chain. l't is also apparent that the dcvice in its improved form can be manufactured and sold at relativcl)v small cost.

While l have herein shown and described tl e preferred construction and arrangement o., the various elements employed, it is to he nndeietoofi that the device is susceptible ot considerable modification and l, therefore, reserve the privilege of adopting,v all such legil'inmte changes :ze muy he fairly cmhotlietl v thiri 'the Spirit and :Scope of the invent: es claimed.
